What is the core of artificial intelligence?

1, computer vision

Computer vision refers to the computer's ability to recognize objects, scenes and activities from images. Computer vision technology uses a sequence composed of image processing operations and other technologies to decompose image analysis tasks into manageable small tasks. For example, some techniques can detect the edge and texture of an object from an image, and classification techniques can be used to determine whether the recognized features can represent a class known to the system.

2. Machine learning

Machine learning refers to the ability of a computer system to improve its performance only by relying on data without following explicit program instructions. Its core is that machine learning automatically discovers patterns from data, and once patterns are discovered, they can be used for prediction.

3. Natural language processing

Natural language processing refers to the computer's text processing ability similar to that of human beings. For example, extracting the meaning from the text, or even interpreting the meaning independently from those readable texts with natural style and correct grammar. A natural language processing system does not understand the way human beings process texts, but it can skillfully process texts with very complicated and mature means.

4. robots

Cognitive technologies such as machine vision and automatic planning are integrated into extremely small but high-performance sensors, brakes and cleverly designed hardware, thus giving birth to a new generation of robots, which have the ability to cooperate with human beings and can flexibly handle different tasks in various unknown environments.

5. Speech recognition

Speech recognition mainly focuses on the technology of automatically and accurately transcribing human speech. This technology must face some problems similar to natural language processing, and there are some difficulties in dealing with different accents, background noise and distinguishing homophones ("buy" and "by" sound the same). At the same time, you need to keep up with the normal speech speed.
